The printed circuit boards are made in the USA, the costs are $5/sq in with no setup fee for two-layer PCB designs. Four layer boards run more but still quite affordable. You order PCBs in sets of three. And the soldermask is a nice, custom purple! ooooo....!

I've been using DorkbotPDX now OSHpark for a year or so now and have done probably a dozen printed circuit board layouts. Every one has come back with excellent quality. The silk screening is very detailed, the plating is fantastic, the soldermask are always right on. That's what you get when it's made in the USA.

And you get fast turnaround (in the US), usually within a couple weeks. He's now doing so much volume that he's sending 2 or more boards per week to the PCB fabrication company.

Laen reports a very low error rate of about 1 in 10,000. Can't say enough good things about this service and I often prefer to wait a few weeks and just have the board fabricated than etching my own single-layer PCB at home.
